The units people prefer for measurements vary across countries.Traditional units of distance such as the Vanilla parasang reflected how a person could walk in a certain amount of time.In the UK，the yard was considered the base unit of length.Ancient Greeks and Romans measured with the foot,which was based on the length of the average adult man's foot.In modern times,the US redefined the fact as exactly 0.3048 meters in 1959.That is now known as the international fact.
